报告摘要：In the field of integrable system, there is a phenomenon that the solution of bilinear equations can be expressed in the form of determinants, like Wronskian form or Grammian form. Cauchy matrix approach can be used to obtain solutions with Cauchy matrix structure, which is also called the Grammian-type solution. The Cauchy matrix approach is a method of constructing integrable equations from Sylvester equation and dispersion relation.
